Acoustic Energy Loudspeaker AE300 User Manual

							Owner’s manual 
						

							Congratulations on choosing the Acoustic Energy AESPRIT
300, a powerful stand mount two-way loudspeaker which
features metal diaphragm technology and is capable of
outstanding performance. Please take a few moments to
read this manual. The advice it contains will enable you to
get the very best performance out of your Acoustic
Energy loudspeakers.
The AESPRIT 300 utilises metal cone mid-bass drive unit
technology, proven in the AE Reference series. The rigid anodised
alloy cone ensures pure piston action and also acts as a heat sink
for the bonded voice coil. These features provide exceptional
clarity, transparency, dynamics and power handling. The units are
housed within vented polymer chasis reducing stray magnetic flux
to a minimum and increasing power handling.
The tweeter - or treble driver - is a high-quality neodymium unit
with a silk fabric dome integrating smoothly with the rest of the
system.
All drive units are fully magnetically shielded so that the speakers
can be used in close proximity to a TV screen or monitor for AV
applications.
The Acoustic Energy AESPRIT 300 loudspeaker uses quality OFC
internal wiring, which enhances detail and transparency. 
The AESPRIT300s are best heard with the tweeters at, or just
below, ear height when the listener is seated. For serious listening
the grilles are best removed.
Rigid support is essential for the speaker to develop its full detail
and dynamic performance. Rigid stands with spikes, cones or other
methods of secure mounting are recommended. ‘Free-field’ stand
mounting gives improved stereo separation and depth. If 
AESPRIT
300s are shelf mounted the support must be firm; cones are still
recommended beneath the cabinets.
Closeness to room boundaries has a major impact on the low
frequency performances. The speakers should be kept away from
corners (which will produce booming). The speakers can be
positioned fairly close to a back or side wall but should not be the
same distance off the ground as from the rear or side wall.
In the rear port of your AE300 you will find a foam bung. This has
been supplied for tuning purposes to allow for differing room
acoustics and positioning. Removal of this bung will give an
increased bass output where required. Experiment with the best
position to achieve a full, yet clean bass response. Trust your
judgement and ears.
For best stereo imaging the speakers should be as far apart as they
are from the listening position.
Positioning
Introduction 
						

							Bi-amping
Bi-amping adds a second amplifier to the system. One power
amplifier drives the treble section of both loudspeakers; a second
drives the mid/bass sections. 
Note that the shorting links
must be removed. Failure to do so will result in damaging
the amplifiers.
As regards the loudspeakers, wiring for bi-amping is achieved in
much the same way as bi-wiring. Treble
amplifier positive (red) 
terminals should be connected via the
ribbed cable to the positive (red) HF
terminal on the speaker. Similarly, treble
amplifier negative is connected to the
negative (black) HF terminal on the
speaker. Repeat this process with the
mid/bass amplifier and LF terminal pair.
After wiring up
Lower the volume to the 
minimum, switch on the 
amplifier, select the signal 
source and then raise the 
volume to the listening
level required.

RLMAIN
Check that your amplifier is switched off before installing your
loudspeakers. Failure to do so may result in speaker or amplifier
damage. The diagram illustrates one loudspeaker only.
Conventional
Normal passive wiring requires shorting links to be in place
between the treble and mid/bass sections. The positive (ribbed)
cable from the amplifier positive (or red) terminal should connect
with the positive (red) terminal on the loudspeaker. Similarly the
negative (smooth) cable should connect the amplifier negative
terminal (black) to the negative terminal (black) on the loudspeaker.
Bi-wiring
Bi-wiring separates the bass and treble ground paths in the
loudspeaker and offer sound quality advantages. An extra set of
cables is required. Note that the shorting links are removed between
the treble and mid/bass sections and should be stored for later use if
conventional, passive driving is required.
Two pairs of cables are connected to the amplifier terminals. One
cable of each pair should connect to the treble section and one to
the mid/bass section. The positive (ribbed) cables from the
amplifier positive (or red) terminal should connect with the positive
(red) terminals on the loudspeaker. Similarly the negative (smooth)
cables in each pair should connect the amplifier negative terminal
(black) to the negative terminals (black) on the loudspeaker.
